Mutual engagement between psycholinguistic and variationist sociolinguistic research is important: work to date shows quite different outcomes from these approaches. This chapter illustrates that, in general, heritage speakers maintain the grammaticalstructures and vocabulary of homeland varieties, in contradiction to widely held beliefs that language quickly “degrades” or is “bastardized” in immigrant communities, and in contradiction to many published studies about heritage languages. However, both approaches converge on finding change in one phonetic pattern in some of the languages analyzed. In this chapter, the potential sources of this apparent contradiction are explored, considering differences related to population, sample, methods of data collection, analysis, and predictors. This allows us to better understand whether, for example, reported “deficits” among heritage language speakers might be partly due to a deficit in test-taking and experience with formal contexts in the heritage language. It closes with a proposal for more coordinated work across methods.
Differences in equilibration rates among crystals of different sizes may be used to deduce paleofluid changes over time if the crystal-growth mechanism is known. To explore isotopic equilibration rates as a function of illite growth, we studied B-isotope changes during illitization of smectite. Montmorillonite (<2.0 µm SWy-1, K saturated) was reacted with aqueous boric acid (1000 ppm B) at 300°C, 100 MPa in sealed Au capsules (1:1 fluid:mineral ratio). The initial fluid was 0‰ (NBS 951 standard) but after R1 ordering occurred (65 days of reaction) the fluid was changed to −7‰ in order to examine the rate of isotopic re-equilibration. Samples were taken intermittently throughout the experiment. Each aliquot was NH4 exchanged and size separated into fine (<0.2 µm), medium (0.2–2.0 µm) and coarse (>2.0 µm) fractions. The isotopic composition of B in the tetrahedral sheet was then measured for comparison with the predicted equilibrium values.
The fine fraction showed equilibrium isotope ratios within 10 days, indicating that small, newly nucleated crystals precipitate in equilibrium with the fluid under supersaturated, closed conditions. These fine-fraction minerals did not re-equilibrate when the fluid was changed. The medium fraction gradually equilibrated with the initial fluid as illite grew to values >50%, but did not re-equilibrate with the later fluid. The coarse fraction was slow to begin recrystallization, perhaps due to dissolution kinetics of large crystals or the presence of detrital contaminants. However, it showed the fastest rate of isotopic change with crystal growth after R1 ordering. We conclude that at 300°C, the initial B–O bonds formed in illite are stable, and isotopic re-equilibration only occurs on new crystal growth. Therefore, different isotope ratios are preserved in different crystal size fractions due to different rates of crystal growth. Large crystals may reflect equilibrium with recent fluid while smaller crystals may retain isotope compositions reflecting equilibrium with earlier fluids.
Multiple approaches – including observational and experimental – are necessary to articulate powerful theories of learning. Our field’s key questions, which rely on these varied methods, are still open. How do children perceive and produce language? What do they encounter in their linguistic input? What does the learner bring to the task of acquisition? Considerable progress has been made for the development of spoken English (especially by North American learners). Yet there is still a great deal to discover about how children in other populations proceed, especially populations in rural settings. To examine language learning in these populations, we need a multi-method approach. However, adapting and integrating methods, particularly experimental ones, to new settings can present immense challenges. In this paper, we discuss the opportunities and challenges facing researchers who aim to use a multimethodological approach in rural samples, and what the field of language acquisition can do to promote such work.
Intolerance of uncertainty (IU) is a cognitive bias that leads to perception and intolerance of uncertainty and has associated negative cognitive, emotional, and behavioural responses. It plays a strong role in social anxiety disorder (SAD; Counsell et al., 2017). Our experimental study examined the impact of uncertainty related to a social stressor on SAD using a speech task. We examined features of SAD including anticipatory anxiety, anxiety during the task, willingness to perform the task, and avoidance of the task. Undergraduate students (N = 110, 88% female) with significant social anxiety completed a series of questionnaires, then were randomised to one of two conditions related to level of uncertainty about an impromptu speech task. The experimental condition (state IU) did not predict any of the outcome variables, while trait IU significantly predicted anxiety levels. Results indicate that increased uncertainty of a social situation does not impact acute anxiety levels in SAD and reinforce the strong role of trait IU as a transdiagnostic cognitive variable. Neither trait nor state IU predicted the willingness and avoidance variables. Results also highlighted the central role of the experience of anxiety on avoidance behaviours, above cognitive factors such as IU.
This Companion is the first academic introduction to the 1960s/70s 'Krautrock' movement of German experimental music that has long attracted the attention of the music press and fans in Britain and abroad. It offers a structured approach to this exceptionally heterogeneous and decentralized movement, combining overviews with detailed analysis and close readings. The volume first analyzes the cultural, historical and economic contexts of Krautrock's emergence. It then features expert chapters discussing all the key bands of the era including Can, Kraftwerk, Tangerine Dream, Neu!, Faust, Ash Ra Tempel, Cluster and Amon Düül II. The volume concludes with essays that trace the varied, wide-ranging legacy of Krautrock from a variety of perspectives, exploring in particular the impact of German experimental music in the Anglosphere, including British post-punk and Detroit Techno. A final chapter examining the current bands that continue the Krautrock sound closes this comprehensive overview of the Krautrock phenomenon.
Pre-registration has become an increasingly popular proposal to address concerns regarding questionable research practices. Yet preregistration does not necessarily solve these problems. It also causes additional problems, including raising costs for more junior and less resourced scholars. In addition, pre-registration restricts creativity and diminishes the broader scientific enterprise. In this way, pre-registration neither solves the problems it is intended to address, nor does it come without costs. Pre-registration is neither necessary nor sufficient for producing novel or ethical work. In short, pre-registration represents a form of virtue signaling that is more performative than actual.
What is particularly interesting in Quilt (2010) by Nicholas Royle narrating the impossible mourning of a man after the death of his beloved father, is its diverse pronominal shifts (it starts as a first-person narrative before becoming a third- then a second-person one), grammatically reflecting the slow disappearance of the first-person protagonist from the narrator’s position and then from the narrative altogether. The clearly-marked ‘you’ passages in Quilt highlight the ghostly presence of a narrator speaking on behalf of a character who is trying to keep it all together but is slowly losing it. The chapter displays that not only does the novel go down the pronominal hierarchy in the switch from first-person to third-person narrative via the second person, but it also stylistically subverts the Animacy Hierarchy through a generic ‘you’ that knits together different pockets of voices in a most experimental way. Royle’s novel is completed by an afterword calling on to the reader in a classical manner, which serves as a transition to Parts III and IV devoted to this (para)textual call to the reader/viewer.
Responses to experimental writing by Irish women poets have tended to be framed in terms of the American tradition. This has served to obscure the distinctiveness of these poets, both as a strand of the Irish tradition and among themselves, in the highly individual bodies of work produced by Susan Howe, Maggie O’Sullivan, and Catherine Walsh. The American-born Howe has been linked to the Language poets, but represents a complex intertwining of personal history and literary exchanges between Ireland and the United States. With its heavy use of parataxis and open-field poetics, Howe’s work opens itself up to wide historical vistas. O’Sullivan’s work, written from England, also stresses open-field forms while showing affinities with the sound poetry of Bob Cobbing and the ‘antiabsorptive’ poetics of Charles Bernstein. Nevertheless, the connection with the Irish tradition is strongly stressed, as is the case also with Catherine Walsh. Walsh’s writing on Dublin is unique in modern Irish writing, notably in its focus on minority and marginalised communities. In the ‘forms of attention’ required by all three writers, Irish women’s poetry remakes itself in unexpected and fascinating ways.
In the Anthropocene, earth system governance must be effective both within and across identities, and the inescapable equivocality of democratic governance means that discussions can never be closed but merely transformed as old problems and concerns give way to new.The experimental quality that effective environmental governance must possess cannot be a transient quality but, rather, must be a permanent feature of the landscape of democratic decision-making, in which success is realized in a context of identity politics.To take place without distortion and without posing systemic disadvantage, and for intergroup differences to be accommodated, substantial equality of access to decision-making and equitable allocation of fundamental capabilities are essential prerequisites.Institutional arrangements must provide for empowerment of those whose identities are otherwise ill-favored and the embeddedness of environmental decision-making in the communities of fate where people actually determine their shared life experiences.
More than just democracy in the form of aggregation of votes, deliberative democratic practice makes possible the learning, local knowledge, and engagement required by enlightened environmental governance under the conditions associated with the concept of the Anthropocene.
A pan-Asian American poetry has been at the forefront of innovative poetics in myriad ways. This chapter foregrounds the impact the innovative legacies of the 1980s and 1990s have had on early twenty-first-century Asian American poetry. The 1980s and 1990s witnessed within Asian American letters the success of a mainstream lyricism but were also a crucial incubation period for a counter-tradition impatient with mainstream modes of poetic expression. Three major counter-modes have come to characterize some of the finest achievements of contemporary Asian American innovative poetics: a surrealist mode, pioneered by John Yau and practiced by younger poets such as Paolo Javier; a documental mode of postmodern montage, evident in the work of Theresa Hak Kyung Cha, Walter K. Lew, Myung Mi Kim, and Divya Victor; and a phenomenological mode practiced by Mei-mei Berssenbrugge and Sueyeun Juliette Lee.
This chapter examines Hurston’s early dramatic works during the period popularly known as the Harlem Renaissance. It argues that a more comprehensive reading of the Harlem Renaissance must include Hurston’s early career in playwriting and that Hurston’s early plays – Meet the Mamma, Spears, The First One, and Color Struck – reflect key concerns of the Harlem Renaissance period. Within this context and combined with the fairly recent discovery of her plays, a fuller view of Hurston’s efforts becomes possible. Given the role of ritual and vernacular folk idioms that would come to dominate her creative writing and her social science career, Hurston’s early plays can be interpreted as testing ground for the theories of culture she would later develop in her novels and essays.
Angiostrongylus cantonensis causes severe neurological disorders in a wide range of warm-blooded animals, including several avian species. A laboratory isolate of A. cantonensis originating from French Polynesia, genotyped as clade 2, was used to assess the effect of experimental infection in chicken and Japanese quail. Low dose groups of birds were infected orally by 100 L3 larvae, high dose groups by 1500 L3 larvae and the birds in the third group were fed three infected snails, mimicking a natural infection. Clinical signs during the first week after infection, haematology, biochemistry, gross lesions and histology findings were used to assess the pathology of the infection. Some of the infected birds showed peripheral eosinophilia, while mild neurological signs were seen in others. No larvae were observed in serial sections of the central nervous system of infected birds 1 week after infection and no major gross lesions were observed during necropsy; histopathology did not reveal lesions directly attributable to A. cantonensis infection. Our results suggest that galliform birds are not highly susceptible to A. cantonensis infection and open a question of the importance of Galliformes in endemic areas as natural pest control, lowering the number of hosts carrying the infective larvae.
This applied experimental research tested the effectiveness of a universal, student-focused intervention (‘Memory Mates’), specifically focused on supporting students to use attention and working memory strategies within academic contexts, unlike computer-based programs. Memory Mates is presented in the form of icons and explanations, with the strategies embedded within the classroom. Analyses compared the impact of the intervention over 8 months in three schools with three control schools, comprising 13 Year 4 primary school classes. The intervention group students showed a significant improvement in mathematics and spelling; however, there was no differential effect on reading comprehension or academic engagement. Based on the present results, it is contended that implementing Memory Mates within classroom contexts demonstrated promising potential as a new approach to supporting academic progress.
The Under the Radar festival is the result of the politics of a time and place that were reset by 9/11. That is when the USA finally learned that it is not invulnerable at home and that its alliances in art, culture, science, and industry are fundamental to its well-being. Situated at Astor Place, a neighbourhood at the crossroad between New York’s East and West Village, Under the Radar is part of a long history of a place that maps part of the story of American immigration, architecture, urban decay and renewal, the economy, and theatre. The festival pivoted away from American exceptionalism towards the interdependence of the neo-liberal economy by accentuating transnationalism in the context of globalization. Greenwich Village’s intellectual and artistic vibrancy has a history of being in conversation with ideas and experimentation originating in Europe, Asia, Africa, Australia, and the Americas. Under the Radar draws upon and adds to this legacy of place through its presentation of work from all over the world. Diversity at Under the Radar signifies ‘this is us’, not in the sense of either multiculturalism or sameness, but of an inquiry of ideas that shapes our shared human destiny.
The chapter discusses the scientific and pragmatic challenges to be addressed when planning a study of cognitive psychopathology in children. The quasi-experimental nature of this branch of inquiry necessitates careful consideration of the sampling frame, as well as decisions on how to validly and efficiently measure psychopathology. The design should focus on maximizing the internal validity of the cognitive construct, experimental manipulation, and outcome variables. However, the ultimate significance of a study is also directly related its relevance to real world behaviors of interest. Pragmatic solutions to establishing effective recruitment strategies as well as methods to train research assistants and maintain active assent among child participants with emotional and behavioral concerns are also discussed.
How do twenty-first century theatre practitioners negotiate the dynamics of tradition and innovation across the works of Samuel Beckett? Beckett's own tendencies toward fluidity of genre, iteration/repetition, and collaboration – modes that also define the 'experimental' – allow for greater openness than is often assumed. Reading recent performances for creative uses of embodiment, environment, and technology reveals the increasingly interdisciplinary, international, and intermedial character of contemporary Beckettian practice. The experimentation of current practitioners challenges a discourse based on historical controversies, exposing a still-expanding terrain for Beckett in performance.
Once a metamaterial has been conceived, designed and built, its expected properties must be experimentally verified, in order to validate the conceptual analysis leading to it and the construction process used to realize it. Using 3D printing technology is not always a trivial task, especially if the designed microstructures are complex and show large differences in their geometrical and mechanical properties, at lower scales. Moreover, once some specimens are built, some specific experimental apparatuses have to be designed that are able to manifest the specific desired exotic mechanical features which are the target of the whole research effort. Therefore it is not a simple task to prove that the pantographic microstructured metamaterials do really exhibit the behavior which is expected. The gathered evidence which shows the validity of the concept of pantographic metamaterial is carefully presented here.
The US National Institutes of Health (NIH) established the Clinical and Translational Science Award (CTSA) program in response to the challenges of translating biomedical and behavioral interventions from discovery to real-world use. To address the challenge of translating evidence-based interventions (EBIs) into practice, the field of implementation science has emerged as a distinct discipline. With the distinction between EBI effectiveness research and implementation research comes differences in study design and methodology, shifting focus from clinical outcomes to the systems that support adoption and delivery of EBIs with fidelity.
Methods:
Implementation research designs share many of the foundational elements and assumptions of efficacy/effectiveness research. Designs and methods that are currently applied in implementation research include experimental, quasi-experimental, observational, hybrid effectiveness–implementation, simulation modeling, and configurational comparative methods.
Results:
Examples of specific research designs and methods illustrate their use in implementation science. We propose that the CTSA program takes advantage of the momentum of the field's capacity building in three ways: 1) integrate state-of-the-science implementation methods and designs into its existing body of research; 2) position itself at the forefront of advancing the science of implementation science by collaborating with other NIH institutes that share the goal of advancing implementation science; and 3) provide adequate training in implementation science.
Conclusions:
As implementation methodologies mature, both implementation science and the CTSA program would greatly benefit from cross-fertilizing expertise and shared infrastructures that aim to advance healthcare in the USA and around the world.
This chapter summarises the key aerodynamic theory of horizontal-axis wind turbine rotors. The actuator disc concept leads to the relationships between induced velocity, axial thrust, and power extraction. The theory is extended to multiple streamtubes, which, combined with 2D wing theory, establish the basis of blade-element momentum (BEM) theory. A straightforward mathematical treatment of BEM theory is included, with an iterative procedure suitable for coding. Measurements from a full-scale rotor illustrate the applicability of BEM theory but also its fundamental limitations: the latter are described, and measures are outlined to compensate for them in practical BEM codes. Simple relationships are given for the axial and tangential load distributions on an optimal HAWT blade. The structure of the rotor wake is described, leading into a description of vortex-wake theory, which provides a more physically realistic description of the airflow. Vortex wake codes are described in non-mathematical terms. The chapter includes wake measurements from full-scale wind turbines and small models. Vorticity maps from the latter verify the underlying mathematical model of a helical vortex wake.
Research links liberal and conservative ideological orientations with variation on psychological and cognitive characteristics that are important for perceptual processes and decision-making. This study investigates whether this variation can impact the social behaviors of liberals and conservatives. A sample of subjects (n = 1,245) participated in a modified public goods game in which an intragroup inequality was introduced to observe the effect on individuals’ tendency toward self-interested versus prosocial behavior. Overall, the contributions of neither liberal- nor conservative-oriented individuals were affected by conditions of a general intragroup inequality. However, in response to the knowledge that group members voted to redress the inequality, levels of contribution among liberals significantly increased in comparison to the control. This was not true for conservatives. The results provide evidence that differences in ideological orientation are associated with individual differences in social cognition.
